Abstract

L'invention concerne un contenant étiré de forme carrée, ainsi qu'un procédé de moulage de ce contenant. L'invention vise à éviter de manière simple une déformation au niveau de la base d'une boîte. A cet effet, le contenant étiré de forme carrée selon l'invention comprend un panneau inférieur (2) en forme de polygone et une paroi latérale (3) en forme de barquette polygonale. Une moulure en saillie (5) est réalisée sur le panneau inférieur (2), à proximité d'au moins l'une des sections arrondies (4) au bas de la paroi latérale (3), cette moulure en saillie (5) s'étendant parallèlement à la section arrondie (4) à une distance prédéterminée de cette section arrondie. Le panneau inférieur (2) a une forme rectangulaire et des moulures (5) sont disposées le long de la paire de sections arrondies (4) des longs côtés.
